# =============================================================================
# teardown — Registers an after-each test hook.
# =============================================================================
#
# What this teaches:
#   • Test hooks — `teardown` registers cleanup logic that runs after every test case in a `describe` block.
#   • Teardown guarantee — The hook runs regardless of whether the test passes or fails.
#
# Common mistakes:
#   • Confusing `teardown` (teardown) with `setup` (setup) — they run at opposite ends of each test.

# teardown — after-each test hook
#
# GRAMMAR:
#   hookDecl :← 'teardown' block
#
# EXPECTED OUTPUT:
#   No main — declaration or test-runner surface only.
#
# BACKEND:
#   declaration-only test hook (whitelist: teardown/postpara.fab).
